Security considerations for Installation Manager

Store credentials

Store our credentials if we use secured repositories.

• Migrate from key ring files to storage files
• Store credentials

encryptString

Use the encryptString command with the -passwordKey option to encrypt passwords in response files or on the command line.

Command-line mode	imcl command-line arguments
Silent mode	Command-line arguments for silent mode

A package might encrypt and decrypt text before the text is persisted in a response file or in the installRegistry directory. By default, Installation Manager uses a static password key to encrypt the text. This password key might be decrypted and used to decrypt the encrypted text. We can use a different password key to encrypt the text using the -passwordKey option. If we provide a password key, we must start the instance of Installation Manager with the same password key each time to access the encrypted data. The password key must be used when you start Installation Manager in wizard mode, console mode, command-line mode, and silent mode.

You can encrypt a value to use in a response file using the encryptString command. Values that are encrypted in the response file or in the installRegistry directory are specific to a package. For information about the values that are encrypted, see the package documentation.
